Characterization of concrete for fastening systems

One of the most important and widely used construction materials of modern times is concrete. A lot of effort has been made in recent years to study the material and all its related technologies. An example of this is fastening systems which are widely used. Due to their importance regarding the safety of structures and people, numerical models which are able to predict the complex behaviour of such systems were developed. This paper endeavors to promote the application of advanced concrete models by providing a comprehensive set of concrete test data, cast from the same batch. These test data are available for model development, calibration, and validation. Flexure tests of four sizes, confined and unconfined compression tests, as well as Brazilian splitting tests of five sizes, and loading and unloading data are included in the database available at http://www.baunat.boku.ac.at/comprtest.html. For all specimen sets the nominal stress-strain curves and crack patterns are provided
